(KMOV.com) – Metro East drivers commuting to St. Louis may have to pay pick a new way to get downtown.

Starting Tuesday morning, the Memorial Drive exit from the Poplar Street Bridge is no longer operational.

Drivers have three alternative options. They can take Interstate 70 west to get downtown and exit at Pine St. They can also take Interstate 44/55 exit or continue on Interstate 64/40 and take the 9th St. exit

This is the latest change as part of plan to build a park over I-70 to connect downtown St. Louis with the area around the Gateway Arch.
